The yearly global percentage fraud loss was on the downward trend, with only 2013 being an abnormal case. Again, telecom revenues went up gradually from 2008 to 2017. PBX hacking and Subscription fraud appeared for all the years (2013 to 2017) in the top 5 fraud methods, and for fraud types, subscriber/identity (ID) theft was prevalent in 2008 and 2011 but did not show up in the top 5 for 2013, 2015, and 2017. Rather, lately, that is from 2011 to 2017, interconnect bypass fraud and International Revenue Share Fraud (IRSF) have become prevalent. Five fraud types and methods stand out: Subscription Fraud, PBX Fraud, Subscriber/Identity (ID) theft, Interconnect Bypass Fraud (IRSF), and International Revenue Share Fraud.

The general objective of this work was to contribute to the general body of knowledge and research work in the area of post-merger and acquisition organizational performance and performance improvement in the Telecommunications industry. Again, it was also aimed at coming out with conceptual and theoretical frameworks that could be helpful to mergers and acquisition researchers and Telecommunications global firms who acquire Telecommunications companies in Africa or emerging markets, to ensure continuous performance improvement in the short to long term. This work employed purely secondary data from mergers and acquisitions literature and author’s personal experiences of mergers and acquisitions to come out with frameworks. Four theoretical frameworks were developed from the conceptual framework. Each of the theoretical frameworks can be used to determine post-merger and acquisition organizational performance from the perspective of the employee, the customer, and the non-customer. The theories behind the frameworks have also been discussed thoroughly. These frameworks can be employed by any researcher who would like to research into post-merger and acquisition organizational performance.
